A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?

0.15
0.47
0.69
0.79

Answers

Answer 1
It suppose to be 0.47
Answer 2

The probability that a randomly selected voice-controlled television is also connected to the internet is 0.69.

Option C is correct.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

let P(V) is the probability of selecting a voice controlled television

and, P(I) is the probability that a selected television is connected to the internet.

So, the probability that a randomly selected voice-controlled television is also connected to the internet

P(I|V) = P(I ∩ V)/P(V)

P( I ∩ V) = 22%

P(V) = 32%

So, P(I|V) = 22%/32% = 0.6875

The midpoint of AD is C. The midpoint of AC is B. If A is at (-10,4) and D is at (2,12), find the coordinates of B. Group of answer choices (-5,5) (-4,8) (-2.5,9) (7,6)

Answers

Answer:

[tex]B(x,y) =(-7,6)[/tex]

Step-by-step explanation:

Given

[tex]A = (-10,4)[/tex]

[tex]D = (2,12)[/tex]

Required

Determine the coordinates of B

C is the midpoint of AD. So, we calculate the coordinates of C, first.

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]D = (2,12)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]C(x,y) = (\frac{-10+2}{2},\frac{4+12}{2})[/tex]

[tex]C(x,y) = (\frac{-8}{2},\frac{16}{2})[/tex]

[tex]C(x,y) = (-4,8)[/tex]

So, the coordinates of C is (-4,8)

The midpoint of AC is B.

So, we calculate the coordinates of B using:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]C(x,y) = (-4,8)[/tex] --- [tex](x_2,y_2)[/tex]

So, we have:

[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]B(x,y) =(\frac{-10-4}{2},\frac{4+8}{2})[/tex]

[tex]B(x,y) =(\frac{-14}{2},\frac{12}{2})[/tex]

[tex]B(x,y) =(-7,6)[/tex]

Hence, the coordinates of B is (-7,6)

Find midpoint of PQ with endpoints P (0,2) and Q (6,-2)

Answers

Answer:

(3, 0)

Step-by-step explanation:

The easiest way to do this problem is to average the x-coordinates and y-coordinates.

So,  (0 + 6) / 2 = 6/2 = 3 = x   and (2 - 2)/2 = 0/2 = 0 = y

Therefore, the midpoint is (3,0)

Answers

There is no picture or any thing but the graph of a circle is completely determined by its center and radius. Standard form for the equation of a circle is (x−h)2+(y−k)2=r2. The center is (h,k) and the radius measures r units. To graph a circle mark points r units up, down, left, and right from the center.

Herb’s mom is a seamstress. She hems shirts, pants and dresses. For each item she hems she gets paid $1.50. If she hems 45 pieces of clothing each day, how much money would she make after working 30 days?

a.) $2,025

b.) $135

c.) $67.50

Answers

Answer: $2025

Step-by-step explanation:

$1.50. x 45= 67.5 items per day. 30  days is 30 x 67.5= $2025

Answer:

a) $2025

Step-by-step explanation:

The equation you would do is

[tex](45(1.50))30[/tex]

by multiplying 45 and 1.50, you get the price of how much money she makes after one day. in order to find 30 days, just take the product of that equation and multiply it by 30 to get $2025
